(√3-√2)ˇ2×(5+2√6)(√3-√2)ˇ2×(5+2√6)(√3-√2)ˇ2×(5+2√6)(√3-√2)ˇ2×(5+2√6)=[(√3)^2+(√2)^2-2√3*√2]*(5+2√6)=

(√3-√2)ˇ2 × (5+2√6)
(√3-√2)ˇ2 × (5+2√6)

(√3-√2)ˇ2 × (5+2√6)
(√3-√2)ˇ2 × (5+2√6)
=[(√3)^2+(√2)^2-2√3*√2]*(5+2√6)
=(5-2√6)*(5+2√6)
=25-24=1

(/3-/2)^2*(/5+1)^2

(√3-√2)ˇ2 × (5+2√6)
=(5-2√6)× (5+2√6)
=25-24
=1
